Application filed Jane M, 1922.

T all whom it may concern:

Be it known that l, Pn'risn Fnoonrszan, a citizen of Ukraine, residingatliallingford, in the county of Delaware and State of ltennsylvania.have invented certain new and useful improvements in l lying Machines,of which the following is a specification.

This invention relates to certain new and useful improvements in flyingmachines and has particular reference to a machine cmbodying rigid planesections and hingedly mounted wings disposed above the plane sectionsadapted for operation at will of the pilot to sheet a sudden or rapidascension of the plane whenever desired.

The invention further embodies in a flying machine of the type above setforth, the pro vision of devices for connecting the wings to the drivingmechanism for the propeller, and further embodies means for holding thewings rigidly positioned at the desired angle relative to the planesections for operating as a biplane.

The Wing structure presents novel features b the inclusion ofautomaticall o eratin I? y e pipe or damper valves in the wings to beopened against the spring tension thereon upon rlsmg movement of thewings, and

automatically closed when the wings are lowered, thereby offering theleast air resistance to the wings when the same are raised and afiordinga full working surface when the wings are lowered. l

With the above general objects in View and others that will appear asthe nature of the invention is better understood, the same consists inthe novel construction, combination and arrangement of parts hereinaftermore fully described, illustrated in the accompanying drawings andpointed out in the appended claim.

In the drawings forming a part of this a plication and in which likedesignating c' aracters refer to corresponding parts throughout theseveral views.

Figure 1 is a front elevational view of a flying machine constructed inaccordance with the invention, showing the rigid plane sections and thehingedly mounted wings disposed above the plane,

Figure t is a vertical sectional view taken on line lV-llV of Figure 3showing the crank shaft and connecting rods attached to the slidingframe bar for reciprocating the wings and connecting the crank shaft ofthe wing operating mechanism to the driving mechanism of the flyingmachine ropeller,

l igure 5 is a detail sectional view talren on line VV of Figure 3showing the slidin frame bar and the guide bars therefor igure 6 is adetail sectional view talren on line Vl-Vl of Figure l showing themechanism for holding the wings rigidly positioned,

Figure 7 is a detail fragmentary edge elevational view of the slidingframe bar, showing the anti-friction roller carried thereby, and

Figure 8 is a fragmentary detail sectional view of a portion of thewings showing the tension-ed automatically operating damper platecarried thereby.

Referring more in detail to the accompanying drawings, and withparticular reference to Figures 1 and 2, there is illustrated a flyingmachine embodying a fuselage 1 provided with the usual empennage 2- atthe rear end thereof, the power shaft for the motor carried in thefuselage extending through the forward end thereof for sup porting apropeller 3 while rigid planes extending laterally of the fuselage aresuitably braced by truss rods .5, an operators seat 6 being positionedin the fuselage rearwardly of the planes 4- as clearly shown in Figures2 and 6.

A hinged wing structure is supported above the rigid planes 4, astandard embodying a cross head 7 having spaced perpendicular dependingside legs 8 carrying angle feet 9 at the lower ends thereof to besecured as at 10 to the opposite sides of the fuselage l as clearlyshown in l i tires 3 and 4:. A hinged plate 11 is secureg to the upperend of the cross head 7 and has hingedly connected to each side thereof,a wing 12.

The wing is of oval formation in plan view and is curved transversely ofthe ion gitudinal sections thereof, each wing being provided with a pairof openings 13 normally closed by damper plates ll hinged as at 15adjacent opposite sides of said openings, a pair of flat sprin s 16secured as at 17 to the under face of the wing 1.2

the free ends thereof engaging the damper plates 14 for normally holdingthe same in closed position shown in Figure 2.

The operating mechanism for the hingedly mounted wings. 12 includes askeleton frame bar 18 vertically slidable between the side legs 8 of thesupporting frame for said wing, the opposite ends of the frame bar 18being reduced as at 19 and carrying antifriction rollers 20 that engagethe legs 8 as clearly shown in Figures 3, 5 and 7. An attaching clip 21secured to each side of the frame bar 18 has pivotally mounted therein,one end of a link 22 that has the other end thereof pivotally connectedas at 23 to the under face of the wing 12. A shaft 21 having a crankportion 25 is journaled transversely of the fuselage 1 as shown inFigures 4 and 6, one end of the crank shaft 24. carrying a slidin clutchelement 26 for connecting said sha t to the sprocket wheel 27 driven bya chain 28 connected to the motor for operating the propeller 3. 30 atits lower end to the crank portion 25 of said shaft has the upper endthereof pivotally connected as at 31 to the lower side of the frame bar18.

To hold the wing 12 rigidly positioned, when the clutch element 26 isdisengaged from the sprocket wheel 27, the gear wheel 32 fixed tothecrank shaft 24 atone end thereof is adapted to be engaged by the slidingbolt rod 33 guided in brackets 34: as shown in Figures and 6.

In the operation of the device, the propeller is operated by the motorsupported III the fuselage, the rigid planes 4 and the empennage 2controlling the flightof the macllne. When it is desired to suddenlyrise or increase the lifting power of the machine, the clutch element 26is moved into engagement with the sprocket wheel 27 connected to thepower mechanism of the machine, thereby rendering the crank shaft 24operative for vertically reciprocating the same bar 18 and swinging thewings 12 upon their hinge connections with the upper end of the crosshead 7 of the supporting frame as clearly illustrated. During the risingmovement of said wings, the damper A linkrod 29 connected as atplates 14will be opened against the tension of the flat springs 16 to offer theleast resistance to air pressure, and upon downward movement of saidwings, the damper plates will be closed to offer greater resistance tothe air pressure and thereby insure a more certain rise of the machine.The wings 12 may be set in rigid position as indicated by the arrowlines in Figure 1, and so retained by the sliding bolt rods 33 engagingthe gear wheel 32 above the crank shaft 24, such connection beingeffected when the clutch element 26 is disengaged from the powersprocket gear 27. Friction between the movable parts of the device areminimized by the provision of the anti-friction rollers 20 between thecross bar frame 18 and the uide legs 8. I

Wiile there is herein shown and described what is believed to be thepreferred embodiment of the invention, it is nevertheless to beunderstood that various forms, modifications and arrangements of theparts may be made without departing from the spirit and scope of theinvention as claimed.

Having thus described the invention, whatsl claim as new is In a flyingmachine of the type described, a fuselage, a plane section rigidlycarried thereby, a erpendicular guide frame superposed on t e fuselage,side wings hinged to the upper end of the supporting frame, a frame barvertically slidable in said support, link rod connections between theframe .bar andthe wings, a crank shaft journaled transversely of saidfuselage, a link'rod connection between the crank portion of said shaftand the frame bar, and connections between the flying machine motor andthe crank shaft, means for disconnecting the crank shaft from said motorand means for holding the crank shaft rigidly positioned with the wingsimmovable, said last mentioned means comprising a gear wheel fixed tosaid crankshaft, guide brackets carried. by said fuselage, and a slidingbolt rod carried by'said brackets and adapted for engaging said gear forholding the crank shaft rigidly positioned. i

In testimony whereof I aflix my signature.
